New Delhi: The government today said it plans to set up a Centre for Communication Security Research and Monitoring to help security agencies intercept and analyze call details.

Government proposes to set up such a center and intends to keep a copy of select call data records (CDRs) for its use, Minister of State for IT and Communication Jyotiraditya Scindia informed Lok Sabha in a written reply.

"The Centre will provide mandatory access to Law Enforcement agencies for intercepting, monitoring and analyzing activities of required customers and their social networking, both proactively online and through post analysis of information like CDRs."

Complete CDRs are already being maintained by operators for one year as part of license conditions.

Security agencies have been expressing concern over the data sent through the BlackBerry wireless service, as it cannot be intercepted since it is routed through servers in Canada.

The solution for the issue is being worked out as the government is understood to be thinking of asking the BlackBerry to shift their servers to India or copy the data and store them for at least a year for any eventuality.

BlackBerry services are offered by all top carriers Bharti Airtel, Vodafone Essar, BPL and Reliance Communications. Government is already believed to have asked operators not to provide certain BlackBerry services until adequate monitoring systems are put in place.
